I think the article misses the key selling point of VPLS which is separation of routing from customer and provider, in which case there should never be any reason to see broadcast storms inside a VPLS when all CE devices are L3.  

In general it's a good practice to implementing MAC-limiting on VPLS PE anyway so that only a single MAC is learnt from the customer (being the CE router's WAN-facing interface) which ensures they don't cause grief when they accidentally plug in a switch.

Bridging multiple sites over a WAN is always fraught with danger, but certainly works when design and scaling is well thought out.

Cheers,

Ben
